I received a letter in the mail in the beginning of April about a recall. The Slave Cylinder just happened to go out at this time, so I tow it in to Kia Downtown LA on April 6th. I let them know I have recalls on the vehicle and the problem with the clutch, or more specifically the slave cylinder. They give me a estimate on how much it would be to replace the slave cylinder, so I decline the offer and asked them to just get the recalls done. That was on April 13th. We have this back and forth phone calls about when was I going to pick up my vehicle and I had to constantly remind them that I was waiting on them to call me letting me know when the recalls were finished. It took until April 22nd to find out that none of the recalls were done, after being told they are "still working" on the recalls. I go to pick up my car asking about why none of the recalls were done and their excuse was they could "not turn it on, the car was shaking, or because the clutch issue." I had to pay a fee of $189.95 for the "diagnostics" and in order for them to release the car. I get the car fixed as of June 3rd, and on that day the engine locks. The component that failed is the 'knock sensor detection system' which could have prevented the engine from locking or worst catching on fire. I very much feel that me, my spouses, and others around me on the road were not safe. There was no warning lamps on or messages on to indicate the engine was under any problem. At the same time the oil had been changed on April 1st, and they gave no indication that the car was ever leaking oil. As of June 10th the car was towed into the dealership again. I have called every day they were open, and finally got a hold of a advisor on June 13th. The same advisor as the one I had last time. He now alleges the technician "couldn't get a proper reading from the scanner" last time, and how the "PI 2002" recall has expired so they might not be able to do anything about the engine.

Check engine light came on. Kia dealer ran a diagnostic test on it. Says there is a knock in the lower part of the engine. Expects it is a rod knocking. Found metal filings in the valve oil filter. After replacing that oil filter, valve solenoid and adjusting the valves the check engine light came on again. This time the Kia dealer says the engine needs to be replaced.

On 10/31/20 my 2012 Kia Forte completely died at 49,000 miles while I was traveling at around 45 mph. I lost all power, the engine started smoking badly and I was stuck in the center of a 4 lane road with cars flying past me at around 50 mph. I had to call 911 because I could not get out of the smoking vehicle and I could not get the vehicle out of the middle of the road. The police officers had to do a pit maneuver to get me safely off to the side of the road. The vehicle was towed to the dealership where I originally purchased the vehicle in 9/2017. I was told after inspection that it had a severe knock sensor and catastrophic engine failure. My extended warranty company was charged for the $15000 engine that they replaced And I paid my $100 deductible. Although at the time the service department at Kia knew that this was an engine recall call situation that the manufacturer was responsible for, not my extended warranty company. My Kia forte Was in the shop for 2 months and the 1st engine they replaced did not work properly so they had to put another engine in during that period of time. Kia paid for the 2nd engine that was replaced. On January 27th of 2021 I received a notice from Kia Motors notifying me that my vehicle was part of the fire engine recall. I have had my vehicle in my possession a total of Maybe 380 days out of the last 438 since this happened. Kia corporate and the service parts Manager have been completely uncooperative, deceptive and negligent in their treatment towards me.I have gone through Maybe 25 loaner vehicles, had to bring the vehicle back 30 times, now a 4th engine is in the process of being replaced, I have defaulted on my car payments due to out of pocket expenses charged by Kia, the service department manager has stuck me with a $600 rental bill, a $250 traffic camera ticket, put me in a defective loaner that caused an accident and has now spent probably around 90k on a vehicle that is worth a fraction of that.

I tried starting my vehicle and it wouldn't turn over so I pulled the key out of the ignition and the engine kept running. It stopped quickly, so I thought it was weird so I tried again and it made the same vacuum type noise and started smoking, all while the key was not in the ignition. It stopped smoking but I walked away for a sec and came back and the entire place was filled with smoke and the engine had then caught on fire. I was in a parking garage so many other vehicles could have been damaged, and people could have inhaled smoke and other things of that nature. I was also concerned that it would explode and cause even more damage. There was no other signs that this would happen, my vehicle had driven fine the morning of. The car is totaled of course and was towed off.

The engine failed and the car broke down while driving one of the busiest highways in Texas. The engine has a risk of catch fire too apparently. I have received a diagnostic from an independent mechanic who was able to confirm the problem as total engine failure due to manufacturer oversight. (H&H Auto Repair, 512.863.4411 located at 2524 N Austin ave. Georgetown, tx 78626) The manufacturer has informed me that i can have it brought of which I will be responsible for towing the car as well as for replacing the engine, expecting to cost several thousand dollars. No police have no been involved and the insurance does not cover mechanical work. There was NO indication at all prior to failure.

Two months after the knock sensor update was completed the motor quit running. Prior to this update the car was running great. Even after the motor bearings supposedly were going bad, the car did not leak or burn oil or antifreeze and had been getting 26 miles per gallon in town. Had we traded in the car before the last update we were offered $5400, now the car is only work $800 in salvage. Kia has refused to assist us in any way on this matter and we are having to seek litigation to get some sort of restitution. If you can help this would be greatly appreciated. When the motor failed the car was traveling at highway speeds and just locked up. My daughter, who is 17 and was driving could have been killed as she had to go from the left lane to the right shoulder without any power or power assisted brakes/steering. This is completely unacceptable and Kia would not offer any compensation in the repair of the vehicle and now is seeking a signature absolving them of any liability in this matter.

Purchased a used 2012 Kia Forte Koup 2.4L on 02/05/21. 4 months later, I was driving vehicle when I experienced engine failure. Towed to dealer who discovered a hole in the bottom of engine block. Needs new engine. Kia tested the ECU and sent the results to corporate Kia. 8 weeks has past with no update on replacing the recalled engine under warranty. Now trying to file claim under extended warranty. Cannot afford to replace engine out of pocket. Engine failed 4 months after purchasing.

Car was stalling. Engine light was not turning on, so I was unclear of issue. Took car to dealership on Tuesday, June 29th, at 9am for repair. Engine has recall. Car has since been at dealership, following repair test failure. Dealership refuses to offer loaner vehicle, but states repairs could take up to 3 weeks, as they have to wait for new engine to be delivered. I am without a vehicle and should not have to pay for a rental, as the damage is fault of Kia.

This complaint it about Kia Motors. My motor sent a rod through the block due to a recall. However, i called a week before because of rod knock that started on 05/22/21(blew 05/27/21), i was told parts were ordered. A week after i was told that the engine blew. I towed it to a dealership (05/28/21) Its been an additonal 2 and a half weeks with no update as to when itll be repaired, no loaner offered. Ive already lost one job because of Kia's lack of quality control. This engine failure is common and i believe common enough to not have to wait this long for work to be done.

2012 Kia Forte Ex 2.0 I4 126k miles Daughter driving car to college, inside of vehicle filled with smoke, car engine stalled while on Hwy 430 in the middle of a construction zone. Barely made it to the shoulder of the road. I was close buy, I went and loaded up the car and took it home. Once home, I turned the ignition to on, to check for warning lights, None present! I looked under the car and could see oil! I looked all over the engine and discovered oil was coming from oil dipstick tube. I pulled the dipstick the rest of the way out and could see extreme metallic particles in oil. I drained what oil was left and the oil pan was full of fine metallic debris. I went ahead and changed the oil and started the car and the engine has an extreme knock, due to a common Kia failure. Faulty Rod main bearings. Contacted Kia and they told me to kick rocks. There-€™re corporate managers stated, -€œ I could care less if you ever bought a Kia and I could care less that the Rod Bearing failure is premature or a design flaw. We will not honor nor fix it.-€ This engine is in multiple Kia brands, they have recalled and replaced thousands of them. Since this engine is in a Forte, they stated my vin wasn-€™t in the selected range of defective engines. Even though, other models with the same engines are! Kia needs to stand behind and fix their faulty engines. My forte never had a -€œcheck engine -€œ light come on. The knock sensor never sent the car into limp mode and the vehicles pcm never acknowledged an issue to alert the driver of an impending disaster. Not only is my engine defective by Kia, they tampered with the vehicles software to where the knock sensor would never sense an impending problem, until the engine exploded in the consumer's face. Otherwise, the knock sensor would have alerted to an impending problem! Not one check engine light, not one ever came on! A computer scan also showed no stored codes, No active fault codes and No pending fault codes.
